PPR
Establishment is intended for management of portable VHF rušičů working in the band 30 - 88 MHz, the interference fónických operations with frequency modulation (F3E) and the possibility of checking the 72 frequencies of the interference of up to 9 (18) frequencies at the same time. The basis of the system form a profitable station R13 with rušícím complement to the compact receiver and the PC.
